As invasive species

Because of the potential to destroy aquatic and marsh vegetation in the wild, the European Union has banned all imports of snails from the family Ampullariidae, which includes the genus ''Pomacea''. Similarly, the United States prohibits all members of Ampullariidae except one from being imported or transported interstate, except with a permit for the purposes of research. The sole exception to this is ''

'' (formerly '' P. bridgesii'') as it is not known to be an agricultural pest.
